6. Functional Description
6-1 System Outline
IMX477-AACK-C is a CMOS active pixel type image sensor which adopts the Exmor RS technology to achieve high
sensitivity, low noise, and high speed image capturing. It is embedded with backside illuminated imaging pixel, low
noise analog amplifier, column parallel A/D converters which enables high speed capturing, digital amplifier, image
binning circuit, timing control circuit for imaging size and frame rate, CSI2 image data high speed serial interface, PLL
oscillator, and serial communication interface to control these functions. When Gyro function is enabled, Gyro control
block in IMX477-AACK-C is processed based on the input data from Gyro IC.
Several additional image processing functions and peripheral circuits are also included for easy system optimization
by the users.
A onetime programmable memory is embedded in the chip for storing the user data. It has 7 K-bit for users,
16 K-bit as a whole.
